A motor-powered windshield scourer for any type of a motor-powered vehicle and or motor craft. The motorized windshield scourer may have a motor propelled appendages or a singular appendage that have replaceable scouring attachments joined to the appendages. The motor that propels the appendages can be positioned anywhere on or in the motor vehicle/craft, whether under the hood, in the cabin or elsewhere. The motor driven appendages with joined scouring attachments may be mounted on the windshield of the vehicle directly opposite of the windshield wiper blades. When turned on, the motor may move the appendages with joined attachments in a side to side and/or up and down motion across the windshield. The appendages may include an unpliable metal such as: steel, titanium, tungsten, or inconel, and the scouring attachments may include nylon scouring pads or a vinyl coated mesh attached to and covering rubber or foam.

A robotic device for providing vertical mobility has a payload is disposed inside a central compartment and supported by a skid. The skid can move up and down through latch and hook pairs to keep intimate contact with the surface and cross over bumps. The apparatus uses a flexible seal to create a reliable vacuum chamber. The flexible seal comprises a foam ring inside fabric pocket. A plurality of rod and spring strips are configured to apply a downward force to the flexible seal to conform with surface curvatures. The fabric pocket fills in the gaps or seams to maintain a vacuum. The air flows inside a manifold and passes through a filter to avoid debris from damaging the vacuum motor assembly.

A self-propelled device includes a body, a walking module, an air extraction module, an air pressure sensor and at least one bumper structure. The body is defined with a first space and a second space in communication with the first space, wherein the volume of the second space is smaller than the volume of the first space and the second space is closer to a side of the body than the first space. The walking module is adjacent to the body. The air extraction module is arranged on the body and is in communication with the first space. The air pressure sensor is arranged on the body and disposed at one end of the second space. The bumper structure is relatively movably arranged on the body, and is configured to close the second space when located at a first position and open the second space when located at a second position. The self-propelled device is for walking on a board surface.

The window cleaning robot according to the invention has an artificial intelligence-controlled moveable washing system which senses such projections as frames, moldings, composite coating materials, etc. on the facades by means of the sensors disposed thereon and which adjusts the positions of the cleaning brushes in a way to contact with the glass surface evenly. It makes the facade cleaning in high-rise buildings safer with the fans adjusting the axial thrust force according to the speed and direction of the wind in a way not to detach from the surface to be cleaned. It allows saving on time, labor force, and costs in facade cleaning. The robot permits performing the cleaning in glass surfaces and facades in a safe manner eliminating the requirement of human factor.

A robotic device for working on a surface includes a body including: a tool for working on the surface; a controller moving the body along the surface; a first set of at least two rotors mounted to the body and generating thrust in a first direction towards the surface; and a second set of at least two rotors mounted to the body and generating thrust in a second direction away from the surface. A sensor measures a distance between the body and the surface, and a computer adjusts the first set of rotors and the second set of rotors in response to the sensor to place the body in position to work on the surface. In particular, the first set of rotors and the second set of rotors generate a net force on the body to it in non-contact position to work on the surface.
